Walbrook

City (EC4) Named from the ancient Wal-brook, or river of Wells, mentioned in a charter of the Conqueror to the College of St. Martin-le-Grand. It rose to the north of Moorfields, and passing through London Wall, between Bishopsgate and Moorgate, ran through the city; for a long time it was quite exposed, and had over it several bridges, which were maintained by the Priors of certain religious houses, and others. Between three and four centuries ago it was vaulted over with brick. the top paved, and formed into the street called Walbrook, and, for a long time past, known only by that name. Sir Christopher Wren lived for many years at No. 5, Walbrook. (Reference: Smith's Streets of London, p. 379)
